Satsuma,
There have already been a number of accidents that have been put down to texting or phone calls at the wrong time, however they have also, like this one, been a part of the problem.
And the communication through the operations desk is all good in theory, however often in the places that I am working, that isn't possible. I often have to climb to an altitude where I can receive messages, and then check them later.
Like I said in my first post, the skill is in deciding what is important and what isn't. As my old instructor said to me, Aviate, Navigate, Communicate. In that order.
